CRUClBLE-SHAKER.

SPECIFICATION forming part of Letters Patent No. 660,386, dated October 23. 1900.

Application filed April 26, 1900- Serial No. 14.389. \No model.)

T0 at whom, it may concern.-

Be it known that I, WILnIAM S. MATHER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Crucible-Shakers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked'thereon, which form a part of this specification.

This invention relates to that class of crucible-shakers shown in my prior application, filed January 20, 1900, Serial No. 2,100; and the specific objects of the invention shown herein are to enable the workman to stand at a distance from the crucible, to enable the crucible to be grasped from the side, to provide grasping means which can be adj ustably tightened upon the crucible, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in theimproved cru cible-shaker and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a perspective view of my improved apparatus as it appears in use. Fig. 2 is a central vertical section on line 00, Fig. 4:. Fig. 3 is a plan of the shaking-tongs. Fig. 4. is a plan of the entire shaker with a crucible in position to be shaken. Fig. 5 is a side elevation of the shaker and crucible looking in the direction of the tongs, and Fig. 6 is a similar elevation in a direction at right angles to the tongs.

In said drawings, a indicates the crucible or melting-pot, which is to be filled while red-hot with metal cut into small pieces and must be shaken at the same time to settle the contents and obtain the maximum capacity of the crucible.

To provide a seat for the crucible which shall preventitsslippingor walkingaround when violently shaken, I use a base-plate b, which is preferably fastened in horizontal position by bolts 1). The crucible sits upon this plaleand is surrounded bya circular row of pins 0, projecting up from the plate sufficiently far to serve as stops to any material lateral movement of the base of the crucible, and therefore arranged as close to the crucible-walls as will permit a ready insertion of the crucible toits seat. Said pins are, inclined outward, as shown, to conform to the swell or bilge of the crucible. Obviously a raised flange around the base of the crucible or a recess to receive the bottom of the crucible or other suit-able retaining means might be used. From said base-plate b a standard d projects upward at one side of the crucible, said standard being preferably provided at its base with afoot d, adapted to be bolted upon the base-plate. This standard is preferably of heavy sheet metal arranged with its flat side toward the crucible and at the upper end provided with longitudinal slots e e open at the top. The slotted standard d thus described serves as a l'ulcrumal support for a tongs-like lever f, employed in shaking the crucible, and which consists of cooperating membersf'f'; pivoted together, as'at g, in any manner common in the art of making tongs. The forward ends of said mem bersf round outwardly apart from the pivotal point 9 on curves which form inwardiy-concave grasping-arms adapted to seize the crucible, said arms each reaching around the crucible about one-third, more or less, of its circumference or far enough to prevent the crucible slipping out between the extremities of the arms.

The rear ends f f of the members f f" extend from the pivotal point 9 away from the crucible to form long handles, which in grasping a crucible are brought close together, as

shown in Fig. 4:, so that they can be held in one hand of the operator.

In using my improved shaker the tongslike lever f occupies a substantially-horizontal position, with the handle ends of the two members f at a point close to the pivot or hinge g lying in the slots 6 at the top of the standard d. The forward arms f 2 grasp the crucibleat a proper point on its height, de-

termined by the height of the standard cl, and the handles f 3 extend rearwardly away from the crucible. The pointg of hinging of the lever members therefore lies between the standard (land the crucible, so thatinadvertent longitudinal movement of the lever is prevented. The lever, however, lies loosely in the slots 6, so that pivotal movementin a horizontal plane may occur, and thus by the operator swinging the outer ends of the handles f 3 from side to side the crucible will be agitated with a rocking motion, which will properly settle the contents.

Obviously a single slot might be used in the top of the standard (I, and the leverf, instead of having the two handles f extending rearward from the junction of the grasping-arms f might be of one integral body part adapted to lie in the single slot. This construction, however, would not adjustably grasp the crucible, and for that reason I prefer the tongslike form shown. Furthermore, the tongsf, which I have shown, can be used, if desired, independent of the standards and base-plate for handling the empty crucibles prior to the filling and shaking operations, thus extending their usefulness.

Other modificationswithin the scope of the claims might be made from the exact construction described without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new is 1. A crucible-shaker, comprising a seat for the base of the crucible, means for preventing lateral displacement of the bottom of the crucible, fulcrumal bearings fixed with respect to said seat, and a shaking-lever fulcrumedin said bearings and having bent arms adapted to grasp the crucible, substantially as set forth.

2. A crucible-shaker, comprising a baseplate adapted to support the crucible, means on said base-plate for preventing lateral displacement of the crucible-bottom, a standard at one side of the base-plate, and a leverfnlcrumed upon said standard and having arms to grasp the crucible, substantially as set forth.

3. A crucible-shaker, comprising means for preventing lateral displacement of the bottom of the crucible, a fulcrumal support, and

V a shaking-lever fulcrumed upon said support and having arms for grasping the crucible, substantially as set forth.

4. A crucible-shaker, comprising means for holding the bottom of the crucible against lateral movement but permitting a rocking of the crucible, a fulcrumal standard, and a shakinglever fulcrumed upon said standard and swinging in a horizontal or approximately-horizontal plane, said lever having means for grasping the crucible, substantially as set forth.

5. A crucible-shaker, comprising a seat or receptacle for the base of the crucible and preventing lateral movement of the said base, and a shaking-lever provided with fulcrumal bearings upon said seat or receptacle and having bent arms for grasping the crucible, substantially as set forth.

6. Acrucible-shaker, com prisinga seat preventing lateral movement of the base of the crucible, a fulcrum fixed with respect to said seat and a shaking-lever having adjustable arms for grasping the crucible, substantially as set forth.

7. A crucible-shaker, comprising a seat or receptacle for the base of the crucible, a fulcrumal standard stationed near said seat and slotted at its upper end, and a shaking-lever fulcru med in the slot having means forgrasping the said crucible,subst-antially as set forth.

8. A crucible-shaker, comprising a base-'- plate upon which the crucible may stand, a fulcrumal standard stationed near the point of the base-plate on which the crucible may stand and having parallel slots at its upper end, and a shakinglever having approximately-parallel members each of which lies in a slot and having means for grasping the crucible, substantially as set forth.

9. In a crucible-shaker, the combination of a base-plate having a circular row of upwardlyprojecting pins, a slotted standard near said pins, and ashaking'leverfulcrumed in said slotted standard and having means for grasping the crucible, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of April, 1900.
